Abstract

The invention relates to a compound rear protective plate of a truck. The rear protective plate is composed of a collision bumper and at least two steel plates, wherein the outermost layer of the steel plate consists of a gel coat layer, a structural layer, a gluing layer, a base coat layer and a steel plate layer; the steel plates are parallel to each other and gaps are arranged among the steel plates, and the gaps are larger than 2cm and smaller than 8cm; the gel coat layer is of neopentyl glycol-o-phthalate resin, the structural layer is composed a plurality of epoxy furan resin layers and fibrages, and both the gluing layer and the base coat layer take the epoxy furan resins as the major material; and the collision bumper is a hydraulic buffer. The rear protective plate has favorable gloss, colorableness and favorable properties such as water proofing, chemical resistance, corrosion resistance, wear resistance, impact resistance and the like, is light in weight and favorable in collision rebound resilience, can effectively prevent small impact and buffer huge impact and vibration, and simultaneously protects the collision bumper. To sum up, the compound rear proactive plate of the truck has the advantages of safety, high efficiency, light weight, corrosion resistance and beautiful appearance.

Description

A kind of compound rear protective plate of truck

Technical field

The present invention relates to a kind of device that is arranged on afterbody behind the transport truck; When car and lorry knock into the back, can reduce personal casualty and vehicle damage effectively, have the two-way prevention function; Take precautions against the loss heavy, that especially big traffic accident caused effectively, belong to the automotive safety protecting component.

Background technology

At present, automotive traffic accident takes place again and again, comprising a large amount of rear-end collision accidents, especially with the dolly load-carrying lorry that knocks into the back; The accident consequence is extremely serious, and the distortion of accident dolly operator's compartment jeopardizes chaufeur life; The consequence of this accident is relevant with the structure of lorry afterbody, and the lorry center of gravity is higher, and the railway carriage bottom space is bigger; The space of railway carriage tail bottom is the root of accident serious consequence of knocking into the back, and improves the lorry tail structure, can play a positive role for reducing the rear-end collision consequence.

Make a general survey of the transport truck of the various trades mark, various tonnage, each producer, all do not have the external security protective device, during use for safety; How voluntarily at automobile tail mounting shaft font or stripe shape Bumper, install owing to be mostly self manufacture, not only outward appearance is indecency; Use inconvenient; And function of safety protection is low, in when, car taking place knocking into the back when, during car to car impact owing to be provided with the stripe shape metal piece; Often increase personnel's the injures and deaths and the damage of vehicle, do not see that still safeguard function is good at present, be used for the product that the transport truck outside prevents the safety device that car knocks into the back.

Summary of the invention

The objective of the invention is to provide a kind of novel structure, reasonable in design, make easy, easy to use, have the generation that safety performance is good, the anticollision ability high, can prevent the car rear-end collision, make personal casualty, vehicle damage reduce to transport truck safety guard minimum, that can vigorously promote the use.

The technical scheme that adopts is:

A kind of compound rear protective plate of truck is made up of collision bumper and two block plates at least, it is characterized in that: the outermost layer steel plate is made up of gel coating resin, Structural layer, adhesive layer, prime coat and steel plate layer.Each steel plate is parallel and have the gap, and the gap should be greater than 2cm less than 8cm; Gel coating resin is neopentyl glycol-adjacent benzene type resin, and Structural layer is made up of multilayer epoxy furane resin layer and fibrage, and it is major ingredient that adhesive layer and prime coat all adopt the epoxy furane resin, and described collision bumper is a water bumper.

The said structure layer is preferably 5 layers, i.e. resin bed, fibrage, resin bed, fibrage, resin bed; Described resin is 70 gram epoxy resin E-44s, 30 gram furane resin YT, 15 gram epichlorohydrin, 30 gram polyethylene polyamines; Described fibrage is reinforced plastic glass fibre cloth or felt.

Above-mentioned adhesive layer prescription be 70 gram epoxy resin E-44s, 30 gram furane resin YT, DMP-30 be 4-10 gram, furfural 25-50 gram, ethylene diamine 15 grams, acetone 80, KH-550 be 6 restrain, 703 be that 20-30 restrains;

Above-mentioned prime coat prescription is 70 gram epoxy resin E-44s, 30 gram furane resin YT, acetone 25-40 gram, polyethylene polyamine 12-15 gram, porcelain powder 30 grams.

Above-mentioned water bumper comprises cylinder body, piston rod; The rear end of cylinder body is fixed on a plate, in bar overlapped in bar cover in being provided with in the cylinder body, piston rod were plugged in; The front end of piston rod is fixed with bump rubber; Its rear end is fixed with piston, is provided with spring in the high pressure chest between piston and the rear end of the cylinder block, and interior bar puts and offers a fuel return hole and a plurality of fuel-economizings hole.

Gel coating resin of the present invention and Structural layer manufacture craft are following: at first make mould, prepare resin, glass fabric is cut, drying.On mould, coat mold release then, parch, last gel coating resin two roads, treat its tack-free after; Carry out first and paste, behind basic the curing, add epoxy resin, carry out pasting the second time; Again, the shop glass fabric adds epoxy resin and pastes for the third time; After the curing, repeatedly paste as required or demoulding finishing, process finished product.

The bonding process of Structural layer of the present invention and steel plate is following: with brush surface of steel plate is removed totally, primed twice, the priming paint brushing should be even, must not holiday or trickling; After treating that priming paint is tack-free, brush coating; After treating that glue is tack-free,, wait to solidify the back pressure relief, leave standstill Structural layer and steel plate bonding and pressurization.

The present invention can be used for the side of lorry, thereby closure compartment bottom space to greatest extent, and effectively reduces public safety hidden danger, alleviates the impulsive force that knocks into the back, and reduces the accident consequence that knocks into the back.。

Outermost layer of the present invention is a gel coating resin, and good gloss is arranged, and pigmentable has good water-fast, chemically-resistant, withstanding corrosion, performance such as wear-resisting, shock-resistant, flexible and rebound resilience simultaneously; Structural layer is the reinforced plastic glass fibre layer, and it is anti-corrosion, lightweight, collision rebound resilience are good, can stop little bump effectively; Adhesive layer and prime coat can guarantee that Structural layer becomes one with steel plate and consistent expansion and contraction is arranged; Leaving the space between the steel plate, can cushion huge impact and vibration effectively, is again the protection to collision bumper simultaneously; Collision bumper can not only absorb huge Impact energy, and can most of impact energy be dissipated through the heat energy that the cutoff port absorption is converted into fluid, and buffering efficient and extinguishing coefficient are all very high.

In sum, the present invention is the compound rear protective plate of truck of a kind of safe, efficient, in light weight, withstanding corrosion, good looking appearance.
